Ethereum 在图节点中部署平衡器子图时，如何解决跟踪过滤器不存在的问题？

我已成功安装。之后，我尝试在我的graph节点中部署

子图部署过程：

克隆

安装依赖项

生成图形代码

创建本地节点

在本地部署

部署之后，我的图形节点日志中出现如下错误

获取节点版本

Geth

我需要启用任何类型的API才能成功部署平衡器子图吗？

Geth节点目前不支持

trace\u filter

方法。对于某些子图，如balancer子图，当尝试将其部署到

图形节点

，它将尝试调用此方法

跟踪过滤器

。但由于geth节点没有API支持，graph节点因此面临错误

参考：Geth JSON-RPC不支持

trace\u过滤器

API。 按照链接查找geth节点支持的API

要完全支持图形节点，需要使用奇偶校验节点。已通过奇偶校验支持API

yarn codegen

yarn create:local

yarn deploy:local
